In the operation of machines for punching jacquard cards for subsequent use in automatic embroidering machines an enlarged pattern of the design to be reproduced is mounted upon the pattern board of the pantograph mechanism. The design of the pattern is then traced by the stylus of the pantograph mechanism and the movements of the stylus are transmitted through suitable operating connections, such as rack bars and gears, to the control devices, such as drums, of the punching mechanism, proper provision being made for the reduction in scale which is to be accomplished in the design as reproduced on the embroidering machine. It has been proposed heretofore so to arrange the transmission members between the pantograph mechanism and the control mechanism that the ratio of translation may be changed, this having been accomplished through the coupling of the connections at different points so that they may be lengthened or shortened as required. This arrangement has the disadvantage that in each instance of change the individual parts must first be disengaged and then reengaged in the changed ratio of translation.

In accordance with the present invention the transmission devices between the movable parts of the pantograph mechanism and the control device of the punching mechanism embody a controllable change wheel gearing comprising a plurality of change gear sets of different ratio one or another of which can be brought into operative relation through a single manual control device at the will of the operator. It is therefore necessary only to bring one of such gear sets of one ratio into operative relation in place of another of different ratio when a pattern of a difierent scale is to be substituted for one previously used or when a change in reduction ratio, as between the. pattern and the embroidery, is to be effected. If there is to be associated with the pattern mechanism and the punching mechanism a control embroidering machine on which, for purposes of checking errors and the like, a single unit of the design is produced on the desired scale, similar gearing, comprising a plurality of change gear sets may be incorporated in the transmission mechanism between the pantograph mechanism and such control embroidering machine so that the frame of the control embroidering machine may be shifted in correspondence with the movement of the pantograph stylus and in accord with the punching of the jacquard cards, and the change gears may be so mounted on the forwardly extending ends of these shafts as to be readily removable. The invention will be more fully explained hereinafter with reference to the accompanying drawings in which it is illustrated, and in which:

Figures 11 and 12 are detail views in section, respectively, on the plane indicated by the lines C--D and EF of Figure 9.

Figure 13 is a detail view in sectional elevation, in a plane parallel to that of Figure 1, of the punching mechanism.

In the drawings the pantograph mechanism is indicated generally at P, the punching mechanism at K, and the control embroidering machine at S, these several mechanisms being operatively connected as will be explained.

The pantograph mechanism P is provided with a pattern board I to which the design 2 to be reproduced is secured, the pattern board being so mounted in the standards 3 as to be adjustable up and down. For the purpose of adjustment it is provided on its rear side with rack bars 4 engaged by gear segments 5 on a shaft 6 rotatably mounted in the standards. t one end, as at the right hand end in Figures 1 and 3, the shaft 6 is provided with a manual lever 1 (shown also in detail in Figures 5 and 6) provided with a spring actuated latch '8 and movable over a stop disc 9 fixedly mounted on the adjacent standard. The disc 9 is formed with notches ll],

Ili Ifl and ll with one or the other of which the latch 8 may be engaged when the lever 1 5 is turned. Through such rotation of the shaft 6 and the gears 5 the pattern board I may be raised or lowered into different adjusted p ositions determinedby thestops ,IO, Ili etc.

In front of the pattern board I are two parallO lel, horizontal but vertically movable tracks ll,

H spaced apart at their ends byvertical members and supported by belts IZ, carried at each end of the panograph mechanism by sheaves I3 and I3 The upper sheaves 13 are connected 15 with each other through a shaft ll ,4fand the lower sheaves 13 through a shaft M "so that equal movement of the sheaves and parallel movement of the tracks along the entire surface of' ;the pattern board in vertical direction are assured.

It will be understood that the needle bodies 24 are frictionally mounted in the carrier and may therefore be shifted with respect thereto as may be determined by the rotary movement of the drums under the influence of the stylus. The effect of such action is to place certain of the needles with the projections 32 of the bodies 24 in line with the heads 3| of the corresponding "punches 28.

The shaft 34, at its other end, has secured to it a large gear 45 which meshes with gears 45 and 45 mounted rotatably on fixed shafts 41 and l' respectively. The control drums 23 23 23, 23 are also mounted rotatably on fixed shafts 5'. and 47*, as shown in Figure 10. As usual in punching mechanisms of the character indicated, the corresponding control drums 23 and 23 can be coupled selectively with the respective gears 46 and 46 through suitable coupling devices 48 and 48 Thereby the horizontal component movement of the pantograph stylus is selectively transmitted in the determined ratio through the shaft 35, the gear 35 and on one or the other of the gears 45, 46 to the drum 23 or the drum 23. In a similar manner the vertical component of the movement of the pantograph stylus is selectively transmitted, in the desired ratio, to the drum 23 or the drum 23 which are also mounted loosely on the fixed shafts ll and t! and can be coupled, through the respective coupling devices 53 and Se with the gears 52 and 62 respectively. To effect this the movement of the horizontal but vertically movable frame ll, H l5 of the pantograph mechanism is transmitted through a vertical rack bar 49 (Figures 1, 2, 4, 11 and 13) carried by the belt 2 at the left hand of the pantograph mechanism to transmission gearing, shown generally at G in Figures 2, 9, 10, 11 and 13, and thence to a tubular housing or sleeve shaft 55 which encloses the shaft 34. The transmission gearing G2 comprises two gears 5| and 52, the hubs 54 of which are formed with annular grooves 53 for engagement by the studs 55 of a lever q shiftable in a vertical plane on an axis 55. By shifting the lever g from one position to the other either the gear 5! or the gear 52 may be brought into engagement with the rack bar 49. The gear 5| is splined on the sleeve shaft 55 so as to rotate therewith but to be capable of axial movement, while the gear 52 is splinled on a rotatable shaft 51 which carries a large gear 58 meshing with an intermediate gear 59 which in turn meshes with a gear 60 on the sleeve shaft 50. A large gear 6| on the sleeve shaft 50 meshes with gears 52, 62 which are mounted loosely on the shafts 47, 41 respectively and may be coupled respectively with the control drums 23 and 23 through suitable coupling devices 53 and 63 respectively. The drums 23 and 23 are thus selectively rotated, at the desired gear ratio, in accord with the vertical components of movement of the pantograph stylus.

It will be understood that the gear ratios of the gearings G and G thus interposed in the transmission devices between the pantograph stylus and the control drums of the punching mechanism must be such that the movements of the rack bars 33 and 49 will be transmitted to the control drums in the desired ratios, change being made from gears of one ratio to the gears of the other ratio by the shifting of the levers g 9 according to the reduction to be effectedbetween the pattern design and the design as reproduced on the embroidering machine.

g It is usual, in shops in which the movements of the embroidery frames are controlled by a jacquard card, to provide in operative relation with each punching mechanism and the corresponding pantograph mechanism a small embroidering machine (indicated generally at S in Figure 1) in order that the operator may be able to see before him a specimen of the embroidery produced under the control of the punching mechanism. It will be understood that the embroidery frame of such control embroidering machine must be moved in exact correspondence with the transmission ratio between the pantograph mechanism and the punching mechanism in both vertical and horizontal directions. At the left hand end of Figures 1, and on a somewhat larger scale in Figure 4 and with the omission of parts which would obscure, there is shown a sufficient portion of such a control embroidering machine as is necessary to enable the operative connections to be illustrated sufiiciently for the purposes of this application. Connected with the vertically movable frame H, ll of the pantograph mechanism, as by brackets 55, is a rack bar 65 which may be brought into engagement with change wheel gearing G (Figures 4 and '7) adapted to transmit the vertical components of the movements of the pantograph stylus in the reduced ratio to a shaft 56 on which are gears 51 (one of which is shown in Figure 4) for engagement with rack bars 58 which carry the embroidery frame of the control or specimen embroidering machine. In like manner the horizontal components of the movements of the pantograph stylus are transmitted by a rod ll (Figure l), of which a rack bar 12 forms a continuation, through change wheel gearing, shown at G in Figures 1 and 4. The movements of the rack bar F2 are transmitted, in the desired reduction ratio, through shaft 13, gear 15 and horizontal rack bar '14, direct to the embroidery frame it to effect the horizontal movements thereof, the frame '15 being guided by rollers 71 in the frame 53 which is guided'by rollers 75, bearing on the standards of the machine for vertical movement.

It will be understood that the change wheel gearing G and the change wheel gearing G are constructed and arranged to operate as already described with respect to the change wheel gearings G and Ci under the control of the manual levers g and g, the change of reduction ratio being effected as to the control embroidering machine by the proper shifting of the levels 9 g and as to the punching mechanism by the shifting of the levers g g Detail description of the change wheel gearings G and G is unnecessary. It will be understood that shifting of the embroidery frame of the control embroidering machine, with consequent adjustment of the punching mechanism, necessitates also a corresponding shifting of the pattern board I of the pantograph mechanism. Such shifting is effected, as already described, through the operation of the manual lever l, the board being secured in its new position through engagement of the latch 8 with the disc 9.

It will also be understood that in the operation of the mechanism when a perforation is to be made in the fabric to be embroidered the pattern board I is raised according to the selected enlargement by 120 mm, or 60 mm., for example. The pantograph stylus being moved across the face of the pattern, the path of such movement is translated to the card to be punched. When the perforation of the material has been completed the pattern board and the stylus are returned to their original positions, the path of the stylus being translated to the jacquard card. The control disc 9 is so formed that it may be placed in engagement in correspondence with the transvided with notches which correspond respectively in position with thereduction of-the design.

It will be understood that various changes in details of construction and arrangement can be made without departing fromthe spirit of the invention as the same is defined in the accompanying claims. t
